SELF-IGNITER FOR GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 737,462, dated August 25, 1903.

Application filed May 27, 1902. $e1'ial No. 109,143. (No model.)

sists of a small ventilator-wheel which is to.

be mounted above the glass cylinder of a gasburner and when rotating thus carries the igniters hanging down therefrom out of the flow of the hot gases for preventing injury t the said igniters.

In the accompanying drawings, Figure 1 shows in vertical section a self-igniting attachment with my improvements; Fig. 2, the plan View thereof. Fig. 3 illustrates in front elevation the construction of the ventilatorwheel shown on a larger scale. Fig. 4 is a vertical section thereof.

In the construction of my invention I use a cylindrical cap I), which is adapted to be placed over the upper end of the glass cylinder a of a gas-burner, so as to cover same partially with its upper conical-shaped end. A needle 0, made of steel or other suitable material, is secured to the said cap and centrally bent up vertically, as shown in Fig. 1, for receiving the ventilator-wheel above referred to. This latter consist-s ofa plurality of wings d--four as shown--made of mica and supported by the arms of an aluminium ring 2, which latter is carried by a small hood g, as shown in Figs. 3 and 4. A glass dab or socket h is concentrically cemented into said hood g or tightened therein by means of asbestos or the like, and a small asbestos ring 2', inserted in the lower end of said hood, provides means for preventing noise from friction when the ventilator is rotating. Ears 'n, extending from the said arm of the ring 6, serve for receiving the loopformed upper ends of two thin wires 70, of a refractory material, which carry the conical aluminium casings Z Z, suspended thereon. Within each of these casings a self-igniting mass 0 is suspended, but having its platinum threads 10 not extending below the lower end of said casing. Openingsm in the sides of said casing Z Z allow a free passage of the gas, thus insuring ignition. The conical upper end of the cap 1) forms a guide for the flow of the gas, which thus is directed against the igniters.

The action of the attachment is obvious. The heat radiating from the flame causes r0- tation of the ventilator-wheel, and thereby the igniters are brought and held out of the flow of the heat by centrifugal force, and thus protected from being worn by the heat.

I claim- In a self-igniter for gas-burners, the combination of a cap adapted to be placed on the upper end of a gas-burner cylinder, a needle vertically and centrally secured thereto, a ventilator-wheel. mounted on said needle so as to rotate freely thereon, a plurality of wires linked thereto and hanging down therefrom, casings secured to the lower ends of said wires and a self-igniting mass within each of said casings, substantially as and for thepurpose described.
